Magpul Industries has now added capacity to produce the much anticipated PMAG 20 M3. The new 20 round magazine brings all of the GeN M3 improvements, including the constant curve geometry and fully anti-tilt, low-friction follower, which is a change from our GEN M2, straight PMAG 20. The constant curve design incorporated in the PMAG 20 M3 results in a shorter length and easier manipulation in the prone position.
